The 4×10″ is very rare format, but anyway, i make also back reduction for 4×5″, 5×7″ and 18×24 cm, obviously all back are magnetic, this is my sign on the camera.

The second accessory is a linhof lensboard adapter from sinar lensboard, by default i make my 8×10 folding camera for sinar lens board 14×14 cm, but, on request, i can make it for other lens board, for example Toyo that is bigger tha Sinar, but also i can make an adapter for linhof lensboard very used from the 4×5″ users.
